Comment (by jlindgren):

 Well, if the goal is to annotate all uses of <AVInputFormat *> with
 <const>, then IMHO it would have been better to start with the functions
 taking such a parameter, and only afterwards move on the the functions
 returning <AVInputFormat *>.

 That way, clients using the FFmpeg libraries could update cleanly to use
 <const AVInputFormat *> everywhere, without adding ugly casts.
